CLIN CANCER RES:SSA联合PRRT治疗晚期胃肠胰神经内分泌肿瘤患者

2018-10-22 MedSci MedSci原创

生长抑素类似物(SSA)和肽受体放射性核素治疗(PRRT)都是晚期胃肠胰神经内分泌肿瘤(GEP-NET)患者的有效治疗方法,但尚不清楚SSA联合PRRT与仅接受PRRT治疗相比是否能延长患者的生存期。CLIN CANCER RES近期发表了一篇文章,研究SSA 联合PRRT治疗对患者是否存在生存获益。

生长抑素类似物(SSA)和肽受体放射性核素治疗(PRRT)都是晚期肠胰神经内分泌肿瘤(GEP-NET)患者的有效治疗方法,但尚不清楚SSA联合PRRT与仅接受PRRT治疗相比是否能延长患者的生存期。CLIN CANCER RES近期发表了一篇文章,研究SSA 联合PRRT治疗对患者是否存在生存获益。

研究纳入了168名在德国波恩大学医院接受治疗的无法切除的GEP-NET患者。将患者分为两组:PRRT单药治疗(N = 81,组1)以及PRRT联合SSA(N = 87,组2),与PRRT联合治疗和/或作为PRRT后的维持治疗。168例患者均可获得总生存(OS)数据,其中160例患者有无进展生存(PFS)数据。第1组的中位PFS为27个月,第2组为48个月(P = 0.012)。第1组中位OS为47个月,第2组为91个月(P<0.001)。第2组死亡率(26%)低于第1组(63%)。SSA与PRRT的联合治疗具有95%的临床获益率(客观缓解或病情稳定),其显着高于第1组(79%)。

文章最后认为,接受PRRT治疗的GEP-NET患者联合进行SSA治疗在肿瘤控制方面具有重要意义。
